SAX解析xml文件

使用SAX解析xml文件：

import java.io.File;

import javax.xml.parsers.SAXParser;
import javax.xml.parsers.SAXParserFactory;

import org.xml.sax.Attributes;
import org.xml.sax.SAXException;
import org.xml.sax.helpers.DefaultHandler;

public class SaxAnalyseXml extends DefaultHandler {

	public static void main(String[] argv) {
		String xmlPath = "E:/test.xml";
		try {
			// build SAX analyse factory
			SAXParserFactory spfactory = SAXParserFactory.newInstance();
			// generate SAX analyse object
			SAXParser parser = spfactory.newSAXParser();
			// assign XML file，XML analyse
			parser.parse(new File(xmlPath), new SaxAnalyseXml());
		} catch (Exception e) {
			e.printStackTrace();
		}
	}

	public void startDocument() {
		System.out.println("start analysis");
	}

	public void startElement(String uri, String localName, String qName,
			Attributes attributes) throws SAXException {
		System.out.println("start node:  " + qName);
		for (int i = 0; i < attributes.getLength(); i++) {
			System.out.println("node property name:  " + attributes.getQName(i));
			System.out.println("node property value:  " + attributes.getValue(i));
		}
	}

	public void characters(char[] ch, int offset, int length)
			throws SAXException {
		//if current node have value,print it
		if(new String(ch, offset, length).trim().length() != 0) {
			System.out.println("node's value:  " + new String(ch, offset, length));
		}
	}

	public void endElement(String uri, String localName, String qName) {
		System.out.println("end node:  " + qName);
	}

	public void endDocument() {
		System.out.println("end analysis");
	}
}
